Gibson Exhaust 66510 Cat-Back Super Truck Exhaust System Stainless Steel

The Gibson Exhaust Super Truck Cat-Back Exhaust System (PN 66510) is a full cat-back performance exhaust system engineered to deliver a deep, aggressive race-rumble tone with real, dyno-verified power gains. Constructed with 2.50-inch 409 Stainless Steel mandrel-bent tubing, this system resists corrosion and maintains precise flow geometry throughout for reduced backpressure and improved exhaust scavenging.

Dual tailpipes exit in front of the rear tires and terminate in a bold 6-inch Polished T304 Stainless Oblong Slash-Cut clamp-on tip, giving your truck a purposeful, aggressive appearance to match its sound. The baffled and chambered Superflow muffler design uses no internal packing material, eliminating the risk of packing blowout over time while keeping interior drone to a minimum.
